The Secret Life Of Chaos.

Chaos theory has a bad name. It conjures up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that humankind has asked for millennia: how did we get here?
Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science, exploring how a universe that started off as dust ended up with intelligent life, and how order emerged from disorder, in The Secret Life Of Chaos.
In the course of a breathtaking 60 minutes, Professor Al-Khalili reveals the science behind the beauty of the natural world and discovers that, far from it being magic or an act of God, it is, in fact, an intrinsic part of the laws of physics.

BelousovZhabotinsky reaction

A BelousovZhabotinsky reaction, or BZ reaction, is one of a class of reactions that serve as a classical example of non-equilibrium thermodynamics, resulting in the establishment of a nonlinear chemical oscillator. The only common element in these oscillating systems is the inclusion of bromine and an acid. The reactions are theoretically important in that they show that chemical reactions do not have to be dominated by equilibrium thermodynamic behavior.
